TECHNICAL FIELD

The disclosed subject matter relates generally to the field of telephony systems. More particularly, the present disclosure relates to a system and method for monitoring telephony communications in real time.

BACKGROUND

Telephony systems are currently available to operate and process the telephony communications across operators (e.g., mobile networks) located in different geographical areas and circles. The telephony communications include audio or video telephone calls, Voice telephone calls (PSTN, VoIP, and IP-IP etc.), conferencing telephone calls, unstructured supplementary service data (USSDs), data related operations (using 2G/3G/4G/5G etc.), facsimile transmissions, cloud telephony operations, text messages, SMS messages, MMS messages, video messages, and all other types of telephony and data communications sent by or received by a user. In an instance, once the telephony communication begins, the calling party's telephony device takes an input provided by the user and converts the input into a stream of data packets that are transmitted over a network. If the telephony communication has been placed to another telephony device, those data packets may be delivered to the called telephony device.

One of the problems with managing telephony communications across the operators is monitoring the various factors involved during interaction flows such as—connectivity, telephone call data validation (telephone call status, Dual-tone multi-frequency signaling (DTMF) correctness, etc.), telephone call quality and more. For instance, detecting the telephone call connectivity issue between the operators in a timely and automated manner becomes critical. In addition to detecting telephone call connectivity issues, there are aspects like validating telephone call status information i.e. whether the telephone number is busy, not reachable etc. In an example, operators have interconnects between each other. Such interconnects and telephony infrastructure which supports the operators can have issues due to the point of interconnect congestion or other faults in the network infrastructure. Various possible error scenarios with respect to telephone calls include but not limited to: telephone calls originating from one operator is continuously failing towards another operator, telephone calls originating from one operator is partially failing towards another operator, telephone calls originating from one operator is connecting to another operator but is not able to sustain a connection i.e. getting dropped after a small time interval, telephone calls are unable to originate from a particular network towards one or more operators and telephone calls are not being received by a network from one or more operators.

Currently, it takes a series of manual efforts to identify telephony communication issues wherein such identifications and escalations to happen very late in point of time. With a telephony system that has the potential to make telephony communication attempts between different combinations of operator telephone numbers, identification of telephony communication-related issues will be quick and easy, thereby speeding up escalation and recovery process.

In the light of the aforementioned discussion, there exists a need for a certain system with novel methodologies that would overcome the above-mentioned disadvantages.

Once the telephony communication monitoring system 108 receives the request for the telephony operations, the telephony communication monitoring system 108 may invoke the involved first user communication devices 102 a, 102 b . . . 102 n and the second user communication devices 104 a, 104 b . . . 104 n depending on the operation using a set of instructions. For instance, to test a telephone call, from the communication device 104 a (belonging to operator foo, telephone number M1) towards the first user communication device 102 a (belonging to operator bar, telephone number N1), the telephony communication monitoring system 108 may be configured to send an instruction to the first user communication device 102 a about an incoming telephone call and wait for the acknowledgment. Once the acknowledgment is received, it may be processed by triggering the telephone call. If acknowledge signal is not received within expiry time or is rejected, it may move to the next available task and retry later once the communication devices 102 a, 104 a become active or available. The signaling may help the first user communication devices 102 a and the second user communication device 104 a to identify that an incoming telephone call from the telephony communication monitoring system 108 is expected and its telephony communication establishment module 202 may perform necessary steps accordingly once it receives the telephone call. Alternatively, remove the interaction and directly trigger the telephony operation i.e., the telephone call from the communication device 104 a towards the first user communication device 102 a. The first user communication devices 102 a, 102 b . . . 102 n and the second user communication devices 104 a, 104 b . . . 104 n may use a local database which regularly syncs up with the telephony communication monitoring system 108 containing a list of monitoring telephone numbers which may be used by the first user communication device 102 a, and the second user communication device 104 a to detect if it's a monitoring telephone calls.

Some example of different possible instructions which the telephony communication monitoring system 108 may trigger along with expected response: a. Are you alive: To verify if the telephone number is active and may communicate to the telephony communication monitoring system 108. The telephony communication monitoring system 108 may be configured to intercept the telephone call from the first user communication device 102 a or the second user communication device 104 a having the telephone number N or M and hang up. The telephony communication monitoring system 108 may be configured to trigger telephone call towards the first user communication device 102 a having the telephone number N1 or M1 from the communication device having the telephone number M1 or N1 and then

i. Wait for hang up or telephone call termination

ii. Wait for pick up->play audio->hang up

iii. Wait for pick up->punch DTMF->hang up

The telephony communication monitoring system 108 may be configured to intercept telephone call from the first user communication device 102 a or the second user communication device 104 a having the telephone number N or M to pick up and wait for hang up. The telephony communication monitoring system 108 may be configured to intercept telephone call from the first user communication device 102 a or the second user communication device 104 a having the telephone number N or M and don't pick up till hanging up. Switch off the communication device having the telephone number for a few minutes (e.g., x minutes) for telephone call status testing.

Each of the instructions may have an expiry time and sequence logic may be decided by the telephony communication monitoring system 108. On receiving the instructions, the first user communication device 102 a and the second user communication device 104 a may acknowledge the instructions and provide result dataset to the result database 304 based on the instructions to the telephony communication monitoring system 108.

Triggering of telephony operations: the telephony communication monitoring system 108 may be configured to trigger the telephony operations among the first user communication device 102 a, and the second user communication device 104 a based on the instruction set. The telephony communication monitoring system 108 may be configured to invoke the telephony communication establishment module 202 of the second user communication device 104 a to trigger the monitoring telephone call towards the first user communication device 102 a i.e., the outgoing telephone call for the second user communication device 104 a and the incoming telephone call for the first user communication device 102 a. The telephony communication establishment module 202 of the second user communication device 104 a may be configured to respond back with the acknowledgment signal denoting whether the telephony operation is triggered, rejected, and successful, etc. The second user communication device 104 a may also be configured to keep updating regarding the progress and termination of telephone call operation i.e., if the telephone call is initiated, in-progress, ringing, cancelled, completed, busy, failed, etc. if origination of monitoring telephone call from the second user communication device 104 a fails, the telephony communication monitoring system 108 may be configured to notify the first user communication device 102 a about such origination failure and the first user communication device 102 a may not expect a telephone call from the telephony communication monitoring system 108 anymore.

An outgoing telephone call for the communication device 104 a: internally once the second user communication device 104 a receives a monitoring telephone call request towards the first user communication device 102 a, the second user communication device 104 a initiates the outgoing telephone call from associated operator-telephone number to be tested as instructed by the telephony communication monitoring system 108.

An incoming telephone call for the first user communication device 102 a: from the moment telephony communication monitoring system 108 triggers the telephone call towards the first user communication device 102 a, it may pass through the network 106. Once the telephone call successfully passes through the network 106, the incoming telephone call may receive to the first user communication device 102 a. Once the incoming telephone call arrives on the first user communication device 102 a, the telephony communication establishment module 202 may intercept the telephone call and verify with the previously received signal to identify it is a monitoring telephone call or not. On identification, the first user communication device 102 a may perform the action as instructed by the telephony communication monitoring system 108 towards the incoming telephone call i.e., to hang up, pick up or perform other operations. The first user communication device 102 a may pass the result of the action and telephone call data to the telephony communication monitoring system 108. In this case, assuming that the communication management system 108 may be signaled the first user communication device 102 a to hang up the telephone call and pass result. The telephony communication establishment module 202 of the first user communication device 102 a, on receiving the telephone call from the second user communication device 104 a, may initiate the hang up instructing the subscriber identification module 206 a and thereby the provider communication device 110 a associated with the first user communication device 102 a to hang up the telephone call.

The first user communication devices 102 a, 102 b . . . 102 n and the second user communication devices 104 a, 104 b . . . 104 n may hide the monitoring telephone call details from the user's telephone call log by deleting such records as soon as it identifies it as a monitoring telephone call.

Termination and result of telephony operations: on successful hang up, the first user communication device 102 a may pass the result with telephone call data to the telephony communication monitoring system 108, in this case marking it as ‘success’ that a telephone call may be indeed received from the first user communication device 102 a as expected. Post hang up by the first user communication device 102 a, the signal may be relayed to the second user communication device 104 a as well about the hang up through the network 106 and it may thereby inform the telephony communication monitoring system 108 that operation is complete and the telephone call status marked as hang up from the first user communication device 102 a. The logic module 310 may be configured to combine the results and data from the first user communication device 102 a and the second user communication device 104 a, marking the connectivity and data correction as successful. The result may be saved in the result database 304 for further scheduling, reference, and actions. For connectivity monitoring user-case of the telephony communication monitoring system 108, it may capture results data in pair's operator combinations using a matrix (e.g., M×N matrix) where columns may represent all originating operators and rows may represent all receiving operator.

Each of the cells in an M×N matrix may be a unique combination of operators across geographies (who can be usually represented uniquely using MCC-MNC code), an entry in each cell may represent the connectivity at any instance of time (UP/DOWN). Similarly, each individual cell may also contain details for other telephony operations and results like telephone call quality measurement, connectivity strength, percentage failure rate, telephone call properties correctness etc. Similarly, data may be captured in any other form as well. The scheduling module 308 may be configured to consider various parameters and decide which telephony operation to perform. The first user communication devices 102 a or 104 a may be configured to consider the operator combination using the parameters. The parameters may include but are not limited to, telephone call volume between operators, prioritization order, the freshness of old result, and previous test results if tests recently failed or passed. The data module 312 may include databases of functional features. The telephony communication monitoring system 108 may be configured to receive the input information from the scheduling module 308 or the interface module 306 (e.g., ad hoc requests, API requests, etc.) to test the telephony operations, in this case, the telephone call between two operators for connectivity measurement. The scheduling module 308 may schedule different telephony operations as well as different measurements apart from the connectivity. For an instance, the communication device having the outgoing telephone number to be 011XXX (e.g., a first telephony communication provider) and the communication device having the incoming telephone number to be 0992XXX (e.g., a second telephony communication provider). The telephony communication monitoring system 108 may identify which entity owns the telephone numbers and initiate invocation towards the entity. The telephone number 0992XXX belongs to the second telephony communication provider which telephony communication monitoring system 108 identifies to be owned by the user and the telephone number 011XXX belongs to the telephony communication monitoring system 108. The telephony communication monitoring system 108 may ping the telephone number 0992XXX to the communication device to check its availability and also inform the monitoring telephone call to the communication device from the telephone number 011XXX within an expiry time. The telephony communication monitoring system 108 may initiate a request to the outgoing telephone number 011XXX for triggering the monitoring telephone call towards the telephone number 0992XXX. On successful acknowledgment, the telephone number 011XXX telephone call may be propagated through various channels and receive to the communication device belonging to the telephone number 0992XXX. On failure case, the telephony communication monitoring system 108 owning the telephone number 011XXX acknowledges back that telephone call is failed to mention reason for telephone call failure status which is recorded by the telephony communication monitoring system 108. On the successful case, once the incoming telephone calls are received to the communication device having the telephone number 0992XXX, the telephony communication establishment module 202 intercepts the telephone call and matches it with the information provided by the telephony communication monitoring system 108. On successful identification by the communication device having the telephone number 0992XXX as the monitoring telephone call from the communication device having the telephone number 011XXX, the telephony communication establishment module 202 performs the hangs up action in the background as per instructions from the telephony communication monitoring system 108.

On successful hang up, the communication device informs the telephony communication monitoring system 108 that it indeed receives a telephone call from the communication device having the telephone number 011XXX and provide details on the telephone call data. At the around same time, the communication device owning the telephone number 011XXX also informs the telephony communication monitoring system 108 of completing the telephone call towards the computing device having the telephone number 0992XXX along with telephone call data. The telephony communication monitoring system 108 may be configured to record such results in the database and repeat testing of other combinations of operators or other telephony operations. Similarly, the outgoing telephone number may belong to the communication device and the incoming telephone number may belong to another communication device.
